OBC's MPG not working, worth fixing?--Solved

The MPG indicator on the OBC of my 2002 325 has been stuck at 21.1 for about a week or two. All other functions work. It has been reset to Zero, but comes back to 21.1 mpg.
Is there an easy fix or does the total computer have to be reset?

Wife thought that resetting the mileage was same as resetting the OBC's MPG. I reset the MPG, and it seems to be working now.
